Recently I was hospitalized for A-fib, and a nodule was seen on the myocardial perfusion scan CT. It was in the right middle lobe, and 0.9 x 0.5 cm in size.

I was due for my 4-month, initial post VATs wedge, CT a couple days later. This was done with contrast, and was clear. The PA said they couldn’t find the nodule mentioned. I am grateful, but wonder how the Echo could have shown a nodule that was not there two days later.

Do CT scans sometimes show nodules that don’t really exist? The Squamous nsclc had been in my right lower lung.

I’d also be wondering about the same question if I were in your shoes, atrooper. Do you have a copy of the ct scan reports? Does the second report mention the results of the previous report and make a comparison? If so, then I would tend to trust the results of the second report. If not, I would ask for an addendum to the report to specifically address the question of this nodule.

Welcome to GRACE. Although it would be good to seek clarification regarding whether the nodule was seen on the second CT and left off the report in error, digital imaging does at times show what are called “artifacts”, which can be loosely defined as digital “noise” on an image. In such a case, there really isn’t anything there.

I appreciate your comments. The CT follow-up mentions it’s compared to the lung screening CT of 12/5/2017 when the lung cancer was first discovered. When I was told the scan was clear, the PA said they couldn’t find the nodule mentioned. I’m hoping it was just “noise”.
